To replace signal and function modules of an S7-400, perform the following steps:

Step

What to do?

How does the system react?

Disconnect the module from its peripheral

power supply, if necessary.

Disconnect the front connector and wiring.

•

If the affected module can generate

diagnostic interrupts and if diagnostic in-

terrupts are enabled as per configura-

tion, a diagnostic interrupt is generated.

•

Call OB 122 if you are accessing the

module by direct access

•

Call OB 85 if you are accessing the

module using the process image

Remove the failed module (in RUN mode).

•

Both CPUs generate a remove/insert

interrupt and enter the event in the di-

agnostic buffer and the system status

list.

Insert the new module.

•

Both CPUs generate a remove/insert

interrupt and enter the event in the di-

agnostic buffer and the system status

list.

•

Parameters are assigned automatically

to the module by the CPU concerned

and the module is addressed again.

Plug the front connector into the new mod-

ule.

•

If the affected module can generate

diagnostic interrupts and if diagnostic in-

terrupts are enabled as per configura-

tion, a diagnostic interrupt is generated.

13.1.4

Replacement of a communication module

This section describes the failure and replacement of communication modules for

PROFIBUS and Industrial Ethernet.
The failure and replacement of communication modules for PROFIBUS DP is detailed in

Replacement of a PROFIBUS DP master (Page 234).
